公共空间中利用空间分布式多显示屏标识的视觉运动诱导行人轨迹调制

多显示屏标识（MDS）如今在城市环境中无处不在，具有影响公共空间中人类行为和体验的潜力。然而，尽管其具有呈现空间分布式动态视觉刺激的独特能力，目前其使用主要局限于广告。在本研究中，我们提出了一种基于感知的方法，用于横向调制行人轨迹，作为公共空间中引导行人的非语言手段。该方法受vection（自运动错觉）的启发，使用横向移动的单色条纹（vection研究中的标准刺激），通过空间分布的显示屏呈现，以引发可能使行人轨迹产生偏差的姿势反应。我们通过受控实验室实验和在国立博物馆中涉及实际行人流的真实世界现场部署来评估该方法。实验室实验考察了MDS设置是否引发与先前关于vection行为影响研究预测方向一致的行人轨迹偏移。现场部署调查了在更接近城市公共空间条件的无约束移动过程中，聚合行人行为中是否会出现类似效果。在实验室中，全屏运动显著使步行轨迹偏向视觉运动方向，而部分条纹运动未产生显著方向效应。在现场部署中，相反的全屏运动条件在聚合行人位置上产生了方向一致的差异。尽管真实世界行人流存在显著变异性，现场结果仍扩展了受控实验室发现，并提供了支持在公共环境中基于MDS进行实际行人调制的生态有效证据。结果进一步表明，足够的视觉运动覆盖可能很重要。

英文摘要

Multi-display signage (MDS), now ubiquitous in urban environments, has the potential to influence human behavior and experience in public spaces. However, despite its unique capability to present spatially distributed dynamic visual stimuli, its current use is mainly limited to advertising. In this study, we propose a perception-based approach for laterally modulating pedestrian trajectories as a nonverbal means of guiding pedestrians in public spaces. The approach is motivated by vection, the illusion of self-motion, and uses laterally moving monochrome stripes, a standard stimulus in vection research, presented across spatially distributed displays to elicit postural responses that may bias pedestrian trajectories. We evaluated the approach through a controlled laboratory experiment and a real-world field deployment involving actual pedestrian flows in a national museum. The laboratory experiment examined whether the MDS setup induced trajectory shifts in the direction predicted by prior research on the behavioral effects of vection. The field deployment investigated whether comparable effects would emerge in aggregate pedestrian behavior during unconstrained movement under conditions closer to those of urban public spaces. In the laboratory, full-screen motion significantly biased walking trajectories in the direction of visual motion, whereas partial-stripe motion produced no significant directional effect. In the field deployment, opposing full-screen motion conditions produced direction-consistent differences in aggregate pedestrian positions. The field results, observed despite the substantial variability in real-world pedestrian flows, extend the controlled laboratory findings and provide ecologically valid evidence supporting practical MDS-based pedestrian modulation in public settings. The results further suggest that sufficient visual-motion coverage may be important.
